As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing robust and reliable power distribution solutions. Our 10kW and 20kW Three Phase Transformers are engineered to meet the demanding requirements of industrial and commercial applications, ensuring stable voltage conversion and safe power distribution. With a commitment to quality backed by a comprehensive 2-Year Warranty and the provision of a detailed Mill Test Report, we offer our global partners not just a product, but a guarantee of performance and transparency.
Our transformers are designed for efficiency and durability. Key features include:
- High-Efficiency Core Design: Utilizes advanced magnetic materials to minimize energy losses, improving overall system efficiency and reducing operational costs.
- Robust Construction: Built with high-grade copper windings and insulated with materials rated for high-temperature operation, ensuring long-term reliability even in challenging environments.
- Flexible Configuration: Available in standard voltage ratios common for industrial use (e.g., stepping down 480V to 208V), with options for custom input/output voltages to suit specific project needs.
- Low Noise Operation: Designed with vibration-damping features and optimized core geometry to operate quietly, suitable for installations near occupied spaces.
- Easy Installation and Maintenance: Features clear terminal markings, accessible connection points, and a dry-type (oil-less) design that eliminates the need for liquid coolant handling, simplifying setup and upkeep.
- Safety Compliance: Constructed to adhere to fundamental electrical safety principles, with optional enclosure protection ratings (IP20/IP23) to guard against dust and moisture ingress.

Frequently Asked Questions (FAQ)
Q1: What is a Mill Test Report, and why is it important?
A Mill Test Report (MTR) is a certified document provided by the material manufacturer (e.g., for the copper or steel used). It details the chemical composition, physical properties, and test results of the raw materials, verifying their quality and compliance with specifications. Having this report for your transformer ensures transparency about the core components' quality, which is crucial for long-term reliability and safety assessments.
Q2: Can these transformers be used outdoors?
Our standard models are typically designed for indoor use. However, we can provide transformers with higher ingress protection (IP) enclosure ratings, such as IP54, which offer resistance against dust and water spray, making them suitable for sheltered outdoor installations. Please specify your environmental requirements during inquiry.
Q3: Are the input and output voltages fixed at 480V and 208V?
No, these are common examples. We manufacture transformers with various primary and secondary voltage combinations to match different regional grid standards and application needs, such as 400V/230V, 600V/240V, etc. Custom voltage ratios are available.
Q4: What does the 2-year warranty cover?
The warranty covers defects in materials and workmanship under normal operating conditions as specified. It typically includes repair or replacement of the transformer if such a defect occurs within the warranty period. Specific warranty terms will be provided with the sales contract.
Q5: How is the transformer cooled? Does it require oil?
These are dry-type transformers. They use air as the cooling medium, with heat dissipated naturally or through convection. There is no insulating oil involved, which eliminates risks associated with oil leaks, fire, and environmental disposal, making them safer and easier to maintain.
Q6: What are the typical applications for a 10kW or 20kW three-phase transformer?
They are commonly used in commercial buildings, small industrial plants, machine shops, data center support systems, and for distributing power within facilities that require a step-down from a higher voltage supply to a lower voltage for equipment operation.
Q7: Can I get a transformer with different mounting options?
Yes. Standard models can be floor-mounted. Wall-mounted versions or models with specific bracket designs can also be produced based on your installation space constraints.
Q8: What information do I need to provide to place an order or request a quote?
Please provide the required power rating (kVA), primary and secondary voltage levels, frequency (50Hz or 60Hz), any special environmental conditions (ambient temperature, humidity), desired enclosure protection, and your preferred shipment destination. This allows us to configure the optimal product for you.
